More information on how client-server Eliom project are compiled on
this page.

If you don't need client-server features, the compilation process is very
simple and without surprise. Compile with ocamlc or ocamlopt
using ocamlfind, with package eliom.server.
You will have to create your configuration file manually.
But you can still use Eliom distillery, which will make easier the inclusion
of client side features, later.
